</table><h2>Description</h2><P>To use JavaScript, you must first open an interpreter session with <i>ejOpenEngine</i>. 
  JavaScript interpreters usually have their own variable and global function 
  name space. To share a variable or function name space, pass a symbol table 
  into <b>ejOpenEngine</b> in the <i>variable</i> or <i>function</i> parameters. 
  If either of these parameters is set to NULL, the symbol table will be created 
  automatically.</P><p>Use <b>ejCloseEngine</b> to close the interpreter when finished. 

<h2>Return Value</h2><p>Handle for the JavaScript interpreter.</p><h2>Example</h2><pre>
if (ejOpenEngine(NULL, NULL)< 0) {
    /* Can't open interpreter */
    return -1;
}
</pre>
